I don't think any street was misplayed "if" we are making the plays for the right reasons.
If our villain is a calling station and will call big bets on draws then we should absolutely blast the pot flop and turn.
If our villain is the type of player to "put us on AK" because we raised preflop and he is a call down monkey with any pair on Aceless and Kingless boards then we should absolutely be blasting the pot every street to include the river.
If our villain is both a calling station and will bluff if he misses his draws then we should bet flop and turn and then c/c river giving him a chance to bluff a busted flush draw.
If our villain is a competent villain that never gets his money in bad, then our turn bet is a mistake since a lessor hand cannot call that turn bet. That is, we only want to make bets that lessor hands can call. But I submit that QJ and KQ can and will often call in this spot on a FD board.
River card sucks because it completes a lot of Qx two pair combos that we beat. Now, out of all the playable Qx hands (KQ, QJ, QT, Q9) that we beat we now lose to half of them
In spots like this on the river one slight angle you can take is to just say, "I missed, good hand you got it..." and then check.
a lot of times villains will check back big hands thinking that if they bet you can't call anyways or if they bluff they will sometimes bluff smaller than they would have.
But back to the hand...
the betting isn't necessarily bad or good until we think behind the thought process for the betting and factor in our villain's competency.
In general, the more competent my villain is, the more I will lean towards smaller bets... Or put another way, I bet in such a way that lessor hands can/will call. The more ******ed my villain, the more I can bet.
